Victory over Swansea yesterday sent Everton up to fourth and continued Martinez's sensational start to life at the club having only lost one match in the Premier League since taking over from David Moyes.

The former Wigan Athletic boss insists the Toffees are not punching above their weight and believes his side's performances this term deserved more than the 34 points gained so far.

Martinez said: "Not at all. What I am very, very interested is with the perception of our fans. Every Everton fan will tell you that the team, if anything, we got less than what we deserve on the pitch.

"The performances have been full of hard work and have been a combination of good flair and good quality football."

“We still believe we can achieve much more in the second half of the season”

Martinez added in an interview with Sky Sports: "You always need to try and fulfil your potential. I would never look at the table in December. December is impossible to set your aim. In a 10-month competition, the margin for error is huge.

"You need to work as hard as you can and get into April and then see the amount of points you've got and then look at the points around and then you can set your target.

"But what is true is that we've got a real exciting group of players, I thought the performances have been magnificent and we can still believe we can improve on that.

"We still believe we can achieve much more in the second half of the season."
